Tunnel in 3 steps
-
Choose how much ETH to send and paste the Bitcoin address that should receive funds on Bitcoin mainnet.
-
Open the order to freeze the quote and reveal a one-time deposit destination.
-
Broadcast ETH to that destination. Once confirmations clear, BTC is pushed to your payout wallet.
Before you broadcast
- Ethereum deposits confirm quickly — usually within a few blocks (~12s each).
- During gas spikes, confirmation cost rises but inclusion remains fast.
- Send ETH on Ethereum mainnet only — not BSC, Base, or other L2s unless your order says otherwise.
- Still waiting on BTC? Give the wallet a few minutes to sync, then share your Exchange ID with support if the order already lists a payout hash.
Ethereum — programmable money on-chain
ETH powers Ethereum mainnet — gas, staking, DeFi, and most smart-contract activity in crypto live here.
Sending ETH to the right network
Use an Ethereum mainnet wallet for deposits. L2 or alternate-chain sends may not be credited.
Leave enough ETH in your wallet to cover gas on top of the swap amount.
Bitcoin — the original digital asset
Since 2009, Bitcoin has been the benchmark cryptocurrency — deep liquidity, wide recognition, and the default on-ramp for cross-chain swaps.
When is my BTC spendable?
After your payout transaction receives the confirmations shown on the order page — typically one or more blocks depending on route.
Checking your BTC payout
- Open the order page and copy the payout transaction hash into a Bitcoin block explorer.
- Confirm the destination address matches your wallet exactly — including case and format.
- Most wallets show incoming BTC after one confirmation; some exchanges wait for more.

Frequently asked questions
Do I need KYC to swap ETH for BTC on TunnelSwap?
No. TunnelSwap is an anonymous no-KYC, privacy-first exchange. There is no account, no ID upload, and no standing balance for Ethereum → Bitcoin swaps.
How fast is a ETH → BTC swap?
Most routes settle within minutes. Final timing follows Ethereum mainnet deposit confirmations and Bitcoin mainnet payout speed.
Does TunnelSwap hold my ETH or BTC?
No. You fund the deposit from your wallet and BTC is sent straight to the address you paste — non-custodial, wallet to wallet.
What if I use the wrong network for ETH?
Only send on the network shown for the order (Ethereum mainnet). Wrong-chain deposits can be unrecoverable — review the safety guides before you broadcast.
